# Bash script to download geoscrub_input table dump (created by AMK) from the
|
|
4
|
# vegbien database, and load it into the geoscrub database (i.e., the
|
|
5
|
# postgis database prepped with geonames.org data, GADM2 data, and
|
|
6
|
# associated mapping tables).

|
# Won't be necessary if we end up injecting all of the geoscrubbing and
|
|
9
|
# geovalidation functionality directly into vegbien itself. And if we
|
|
10
|
# end up implementing this stuff as a standalone service instead, we'd
|
|
11
|
# need to rethink (and generalize) how the input data is handled. But
|
|
12
|
# for now, this should at least serve as a placeholder that could be
|
|
13
|
# tweaked manually to load any arbitrary geoscrub input data table.
